WIRE-TIER FOR SACKS.

Application filed April 28, 1928, Serial No. 273,743, and in Germany September 2, 1925.

This invention relates to an improvement of the commonly usedvwires for tying sacks, in which the ends of the wire are bent to form each a short eye. The ends of the wire are twisted after the middle portion has been placed around the neck of the sack. The twisting is generally done by means of a twisting instrument, having a hook to be inserted into the two eyes. These simple sack-tiers present however the inconvenience that they cut into the sackcloth and destroy the fibres.

A further inconvenience is, that the ends of the tying wire when being twisted are fre quently exposed to excessive stress so that sooner or later the wire will break.

According to the invention the middle portion of the tying; wire consists of two wires lying close together and connected at each end by an-eye so that, instead of a tier of one single wire a double-wire-tier is produced which is used in a similar manner as the commonly used single wire-tier. As the middle portion of the tying wires bears against the sackcloth with a larger surface, cutting into the sackcloth is excluded.

Another advantage is that the windings of the twisted ends are not so steep as in the single wire-tiers, as not two wires but four wires are twisted. The ends of the tying wire are consequently not submitted to excessive stress so that breaking of the tier is excluded and the resistance of the fastening is double as great as hitherto.

An embodiment of the invention is illus trated by way of example, in the accompanying drawing, in which:

Fig. 1 shows the sack-tier, prior to the use.

Figs. 2 and 3 show in side-elevation and top-plan view respectively the tier in the tying position. The tier consists of two parallel pieces b of glowed ironqvire lying close together and terminating at each end in a short eye a, a. The central portion of the double tier is to be wound around the neck of the sack, whereupon the ends are twisted as shown at c in Fig. 2, by means of a twisting instrument of known type, the hooks of. which are hooked into the two eyes a, the other end being hooked in the belt of the workman.

I claim:

A wire-tier for sacks, consisting of a wire doubled upon itself midway and bent so that at the bend a round eye is formed, the free ends of the wire being bent to form together a round eye and then straight pieces which are twisted together to prevent deformation ot the eye at the tying, said double wire-tier designed to be placed around the sack and the two eye-shaped ends to be twisted together.

In testimony whereof I atfix my signature.
